The average motorist often underestimates the power and importance of a spark plug.
Spark plugs must deliver a high voltage spark within milli-seconds in order to ignite the air and fuel mixture inside a vehicle's engine. This process provides the power a vehicle needs to operate.
Old or worn spark plugs can disrupt this process and diminish the amount of power that is generated. According to AAA, old or dirty spark plugs can reduce fuel economy by up to 30 percent.
To keep vehicles running their best, motorists should replace spark plugs according to the intervals outlined in their vehicle's owner manual.

This will not only help drivers see a difference in vehicle performance, but also could save them money at the gas pump.
For years, savvy do-it-yourselfers have relied on this quick and easy maintenance procedure to restore lost power and improve vehicle performance. Now, the average motorist can experience these benefits, too, with a new offering from Autolite.
With enhanced technology for improved durability, Autolite XP Xtreme Performance Spark Plugs are among the brand's most technologically advanced spark plugs.
"We want to give motorists more bang for less buck," said Sean Lyon, Autolite senior product manager.

"Our new Autolite XP Xtreme Performance Spark Plugs offer better overall ignitability and durability while delivering optimum performance for a better overall value."
They are available in stores with an approximate retail price of $5.99 and are backed with a five-year limited guarantee against defects in materials and workmanship. - NU.
